Embodiment
As shown in Figure 1, a kind of energy consumption control system of paint line air painting equipment, comprise and be arranged on the pick-up unit that whether has workpiece on carrier chain for detection of each station of paint line air painting equipment, the PLC being connected with pick-up unit, and a plurality of relays that are connected with PLC, PLC is by the start and stop of corresponding each station motor of Control paint line equipment; When the working time that each station workpiece is set deducts its running time and is more than or equal to setting value; or when the adjacent last station of this station is null signals; PLC switches this station motor to be made it in low frequency running or stopped status; when the working time that each station workpiece is set deducts its running time and is less than setting value; and when the adjacent last station of this station is full position signal, this station motor is in normal operating condition.
Wherein, described pick-up unit adopts approach switch or travel switch.Described carrier chain is gathering chain or self-propelled hoist or suspended chain or skid, possesses frequency conversion function, for delivery of workpiece.Described PLC adopts the PLC of equipment itself or newly increases an independent PLC, possesses following four functions: 1, increased the setting of workpiece at each working procedure duration; 2, increased the workpiece monitoring of each operation actual job time; 3, increased the analysis ability of front and back operation work status; 4, increased the interlock of carrier chain and each motor of application air painting equipment.PLC is to the detection of each operation workpiece practical working situation and comprehensively analyze, and by analysis result feed back to each coating equipment motor,, the result that each coating equipment motor is analyzed according to PLC is again carried out corresponding operation.
The associated motor of application air painting equipment comprises paint spray booth's exhausting blower fan, paint spray booth's breeze fan, spray chamber circulating water pump, scrapes grey grinding chamber breeze fan, scrapes grey grinding chamber exhausting blower fan, strong cold house blower fan is in order better each motor to be controlled, and each motor of coating equipment has increased automatic start-stop function
orfrequency transform function.
The station of common application air painting equipment is priming paint spray station, finish paint spray station, scrape ash polishing station, moisture dry after strong cold station, the strong cold station of priming paint, the strong cold station of finish paint.The strong cold station of priming paint spray station and finish paint of take is below introduced its control procedure as example, finish paint spray station, scrape ash polishing station control mode and priming paint spray station similar, after the strong cold station of priming paint and moisture oven dry, strong cold station and the strong cold station control mode of finish paint are similar, at this, have not just repeated one by one.
As shown in Figure 2, S0: priming paint spray station operation settling signal; T0: workpiece priming paint is dried and set baking time, T1: workpiece priming paint is dried actual baking time; S1: strong cold station occupy-place signal; S2: priming paint drying station occupy-place signal; S3: priming paint spray station occupy-place signal; S4: priming paint spray station motor start stop signal.
Priming paint spray station (three interlocks) course of work: when workpiece enters priming paint paint spray booth, priming paint breeze fan, water circulating pump, priming paint exhausting Fan Equipment starts to run well, employee starts spray painting operation, after having sprayed paint, employee presses " putting car key ", from trend carrier chain, send " operation settling signal ", carrier chain receives after this signal, PLC is dried actual baking time T1 by workpiece priming paint, drying setting baking time T0 with workpiece priming paint contrasts, if priming paint breeze fan, water circulating pump, priming paint exhausting blower fan has been installed in the situation of frequency converter, strong cold station occupy-place signal S1 after T0-T1 >=1 minute or moisture are dried is null signals, priming paint breeze fan, water circulating pump, priming paint exhausting blower fan enters low frequency (about 10HZ) running, T0-T1 < 1 minute, and the strong cold station occupy-place signal S1 after moisture is dried is full position signal, priming paint breeze fan, water circulating pump, priming paint exhausting blower fan keeps running well.If priming paint breeze fan, water circulating pump, priming paint exhausting blower fan are not installed frequency converter, T0-T1 < 4 minutes, and the strong cold station occupy-place signal S1 after moisture is dried is full position signal, priming paint breeze fan, water circulating pump, the continuous running of priming paint exhausting blower fan, when the strong cold station occupy-place signal S1 after T0-T1 >=4 minute or moisture are dried is null signals, priming paint breeze fan, water circulating pump, priming paint exhausting blower fan are closed automatically.When there is room in priming paint drying station occupy-place signal S2, can automatically send null signals and send to PLC, trigger priming paint spray station and put car signal, the workpiece of priming paint spray station moves to priming paint drying station, to PLC, send priming paint spray station occupy-place signal S3 is null signals simultaneously, if the strong cold station occupy-place signal S1 after now moisture oven dry is fed back to null signals, priming paint breeze fan, water circulating pump, priming paint exhausting blower fan keeps low frequency running or stops, if the strong cold station occupy-place signal S1 after moisture is dried is fed back to full position signal, priming paint breeze fan, water circulating pump, priming paint exhausting blower fan runs well, workpiece on strong cold station after moisture is dried moves to priming paint spray station.
As shown in Figure 3, S00: the strong cold station operation settling signal of finish paint; T00: the lower station workpiece of hanging is set the activity duration, T11: lower extension the station workpiece actual job time; S11: finish paint drying station occupy-place signal; S22: the lower station occupy-place signal of hanging; S33: the strong cold station occupy-place signal of finish paint; S44: the strong cold station motor start stop signal of finish paint.
The strong cold station of finish paint (two interlocks) course of work: when workpiece enters the strong cold station of finish paint, PLC starts to monitor the strong cool time of workpiece, when the strong cool time of workpiece reaches setting-up time, PLC is by lower extension station workpiece actual job time T 11, setting activity duration T00 with lower extension station workpiece contrasts, if strong air-cooler has been installed frequency converter, while there is null signals in T00-T11 >=1 minute or finish paint drying station occupy-place signal S11, strong air-cooler enters low frequency running, when T00-T11 < 1 minute and finish paint drying station occupy-place signal S11 are full position signal, strong air-cooler continues to run well, if strong air-cooler is not installed frequency converter, while there is full position signal in T00-T11 < 4 minutes and finish paint drying station occupy-place signal S11, strong air-cooler continues to run well, while there is null signals in T00-T11 >=4 minute or finish paint drying station occupy-place signal S11, strong air-cooler is closed automatically.When on lower extension station occupy-place signal there is null signals in S22 instantly, can automatically send null signals and send to PLC, trigger the strong cold station of finish paint and put car signal, the strong cold station workpiece of finish paint starts to hang station downwards and moves, to PLC, send the strong cold station occupy-place signal S33 of finish paint is null signals simultaneously, if now finish paint drying station occupy-place signal S11 is fed back to null signals, strong air-cooler keeps low frequency running or stops, if finish paint drying station occupy-place signal S11 is fed back to full position signal, strong air-cooler runs well, workpiece on finish paint drying station moves to the strong cold station of paint.
In above-described embodiment, adopt within 1 minute and 4 minutes, be specifically described, its time can be set arbitrarily as the case may be.
